Vi hile I have herein shown and described one particular embodiment of my invention,

I do not Wish to be limited to the precise arrangement shown, since it will be apparent modifications may be made Without deinvention.

I claim: v

1. In combination, a spark plug having-a reciprocating electrode, and a device serving in one position for normally holding said electrode a predetermined distance from the stationary electrode, said device, when moved to its alternate position on said electrode permitting said electrode to be recipfrocated by thefsuction and compression of the engine. l

2. A spaik p lug having a movable inner electrode, a device for maintaining said electrode in its normal position away from the stationary electrode in said plug, said device, when adjusted serving to permit actuation of said movable electrodes that it will frictionally engage the stationary electrode, and packing members cooperating with said movable electrode.

3. In combination, a spark plug having a reciprocating electrode, and a tightening nut for normally holding said electrode a predetermined distance from the stationary electrode, said nut, when moved to its alternate position on saidv electrede permitting said electrodeto be moved by the suction and compression or" the engine.

reciprocating electrode, erated mechanism for normally 'holding said electrode a predetermined distance from the stationary electrode, said mechanism, when `loosened permitting said electrode to be moved up and down by the suction and compression of the engine. Y

In combination, a spark plug having a movable electrode, a stationary electrode projecting into the path of said movable 4. In combination, a spark plug having aY and a manually Op-.

rename the engine, packing members coperating vWith said reciprocal electrode, and resilient means pressing against one of said packing members.

'7'. A spark plug comprising a stationary terminal, an insulating member. provided with inner and outer recesses, a movable terminal adapted in one position to frictionally engage said stationary terminal, a packing member carried on said movable terminal and engaging the inner recess, a spring pressed packing member occupying Vsaid outer recess, a tightening nut having threaded engagement. with said movable terminal, and a Washer carried by said movable terminal Within said outer recess.

8. A spark plug comprising -a stationary terminal, an insulating member provided with inner and outer enlarged bores, a movable terminal adapted in one position to frictionally engage said stationary terminal, a packinginember mounted on said movable terminal and engaging the enlarged inner bore, another packing member occupying said enlarged outer bore, and means Within said outer bore to prevent rotation of said movable terminal.

9. A spark plug comprising a terminal, an insulating member having an outer recess, avmovable terminal adapted in one position to frictionally engage said stationary terminal, a ing said recess, and

stationary a' device Within said repacking' member occupy` cess to prevent rotation of said movable ter- K minal.
